+cross-claim or counterclaim in a lawsuit) alleging that the Work or a
+Contribution incorporated within the Work constitutes direct or contributory
+patent infringement, then any patent licenses granted to You under this License
+for that Work shall terminate as of the date such litigation is filed.
+
+4. Redistribution.
+
+You may reproduce and distribute copies of the Work or Derivative Works thereof

+attribution notices contained within such NOTICE file, excluding those notices
+that do not pertain to any part of the Derivative Works, in at least one of the
+following places: within a NOTICE text file distributed as part of the
+Derivative Works; within the Source form or documentation, if provided along
+with the Derivative Works; or, within a display generated by the Derivative
+Works, if and wherever such third-party notices normally appear. The contents of
+the NOTICE file are for informational purposes only and do not modify the
+License. You may add Your own attribution notices within Derivative Works that
+You distribute, alongside or as an addendum to the NOTICE text from the Work,
+provided that such additional attribution notices cannot be construed as
+modifying the License.
+You may add Your own copyright statement to Your modifications and may provide
+additional or different license terms and conditions for use, reproduction, or
+distribution of Your modifications, or for any such Derivative Works as a whole,
+provided Your use, reproduction, and distribution of the Work otherwise complies

+
+5. Submission of Contributions.
+
+Unless You explicitly state otherwise, any Contribution intentionally submitted

+WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
+including, without limitation, any warranties or conditions of TITLE,
+NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
+solely responsible for determining the appropriateness of using or
+redistributing the Work and assume any risks associated with Your exercise of
+permissions under this License.
+
+8. Limitation of Liability.
+
+In no event and under no legal theory, whether in tort (including negligence),
+contract, or otherwise, unless required by applicable law (such as deliberate
+and grossly negligent acts) or agreed to in writing, shall any Contributor be
+liable to You for damages, including any direct, indirect, special, incidental,
+or consequential damages of any character arising as a result of this License or
+out of the use or inability to use the Work (including but not limited to
+damages for loss of goodwill, work stoppage, computer failure or malfunction, or
+any and all other commercial damages or losses), even if such Contributor has
+been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability.
+
+While redistributing the Work or Derivative Works thereof, You may choose to
+offer, and charge a fee for, acceptance of support, warranty, indemnity, or
+other liability obligations and/or rights consistent with this License. However,
+in accepting such obligations, You may act only on Your own behalf and on Your
+sole responsibility, not on behalf of any other Contributor, and only if You
+agree to indemnify, defend, and hold each Contributor harmless for any liability
+incurred by, or claims asserted against, such Contributor by reason of your
+accepting any such warranty or additional liability.

 //
+// Buffers
+//
+// Connections buffer network input and output to reduce the number
+// of system calls when reading or writing messages.
+//
+// Write buffers are also used for constructing WebSocket frames. See RFC 6455,
+// Section 5 for a discussion of message framing. A WebSocket frame header is
+// written to the network each time a write buffer is flushed to the network.
+// Decreasing the size of the write buffer can increase the amount of framing
+// overhead on the connection.
+//
+// The buffer sizes in bytes are specified by the ReadBufferSize and
+// WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default
+// size of 4096 when a buffer size field is set to zero. The Upgrader reuses
+// buffers created by the HTTP server when a buffer size field is set to zero.
+// The HTTP server buffers have a size of 4096 at the time of this writing.
+//
+// The buffer sizes do not limit the size of a message that can be read or
+// written by a connection.
+//
+// Buffers are held for the lifetime of the connection by default. If the
+// Dialer or Upgrader WriteBufferPool field is set, then a connection holds the
+// write buffer only when writing a message.
+//
+// Applications should tune the buffer sizes to balance memory use and
+// performance. Increasing the buffer size uses more memory, but can reduce the
+// number of system calls to read or write the network. In the case of writing,
+// increasing the buffer size can reduce the number of frame headers written to
+// the network.
+//
+// Some guidelines for setting buffer parameters are:
+//
+// Limit the buffer sizes to the maximum expected message size. Buffers larger
+// than the largest message do not provide any benefit.
+//
+// Depending on the distribution of message sizes, setting the buffer size to
+// a value less than the maximum expected message size can greatly reduce memory
+// use with a small impact on performance. Here's an example: If 99% of the
+// messages are smaller than 256 bytes and the maximum message size is 512
+// bytes, then a buffer size of 256 bytes will result in 1.01 more system calls
+// than a buffer size of 512 bytes. The memory savings is 50%.
+//
+// A write buffer pool is useful when the application has a modest number
+// writes over a large number of connections. when buffers are pooled, a larger
+// buffer size has a reduced impact on total memory use and has the benefit of
+// reducing system calls and frame overhead.
+//
 // Compression EXPERIMENTAL
 //
 // Per message compression extensions (RFC 7692) are experimentally supported

+## Bash legacy dynamic completions
 
-Update the help text show how to install the bash_completion Linux show here [Kubectl docs show mac options](https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion)
+For backwards-compatibility, Cobra still supports its legacy dynamic completion solution (described below).  Unlike the `ValidArgsFunction` solution, the legacy solution will only work for Bash shell-completion and not for other shells. This legacy solution can be used along-side `ValidArgsFunction` and `RegisterFlagCompletionFunc()`, as long as both solutions are not used for the same command.  This provides a path to gradually migrate from the legacy solution to the new solution.
 
-Writing the shell script to stdout allows the most flexible use.
+The legacy solution allows you to inject bash functions into the bash completion script.  Those bash functions are responsible for providing the completion choices for your own completions.
 
-```go
-// completionCmd represents the completion command
-var completionCmd = &cobra.Command{
-	Use:   "completion",
-	Short: "Generates bash completion scripts",
-	Long: `To load completion run
-
-. <(bitbucket completion)
-
-To configure your bash shell to load completions for each session add to your bashrc
-
-# ~/.bashrc or ~/.profile
-. <(bitbucket completion)
-`,
-	Run: func(cmd *cobra.Command, args []string) {
-		rootCmd.GenBashCompletion(os.Stdout);
-	},
-}
-```
-
-**Note:** The cobra generator may include messages printed to stdout for example if the config file is loaded, this will break the auto complete script
-
-
-## Example from kubectl
-
-Generating bash completions from a cobra command is incredibly easy. An actual program which does so for the kubernetes kubectl binary is as follows:
-
-```go
-package main
-
-import (
-	"io/ioutil"
-	"os"
-
-	"k8s.io/kubernetes/pkg/kubectl/cmd"
-	"k8s.io/kubernetes/pkg/kubectl/cmd/util"
-)
-
-func main() {
-	kubectl := cmd.NewKubectlCommand(util.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
-	kubectl.GenBashCompletionFile("out.sh")
-}
-```
-
-`out.sh` will get you completions of subcommands and flags. Copy it to `/etc/bash_completion.d/` as described [here](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) and reset your terminal to use autocompletion. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
-
-## Have the completions code complete your 'nouns'
-
-### Static completion of nouns
-
-This method allows you to provide a pre-defined list of completion choices for your nouns using the `validArgs` field.
-For example, if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like:
-
-```go
-validArgs []string = { "pod", "node", "service", "replicationcontroller" }
-
-cmd := &cobra.Command{
-	Use:     "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
-	Short:   "Display one or many resources",
-	Long:    get_long,
-	Example: get_example,
-	Run: func(cmd *cobra.Command, args []string) {
-		err := RunGet(f, out, cmd, args)
-		util.CheckErr(err)
-	},
-	ValidArgs: validArgs,
-}
-```
-
-Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like
-
-```bash
-# kubectl get [tab][tab]
-node                 pod                    replicationcontroller  service
-```
-
-### Plural form and shortcuts for nouns
-
-If your nouns have a number of aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
-
-```go
-argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
-
-cmd := &cobra.Command{
-    ...
-	ValidArgs:  validArgs,
-	ArgAliases: argAliases
-}
-```
-
-The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
-the completion algorithm if entered manually, e.g. in:
-
-```bash
-# kubectl get rc [tab][tab]
-backend        frontend       database 
-```
-
-Note that without declaring `rc` as an alias, the completion algorithm would show the list of nouns
-in this example again instead of the replication controllers.
-
-### Dynamic completion of nouns
-
-In some cases it is not possible to provide a list of possible completions in advance.  Instead, the list of completions must be determined at execution-time.  Cobra provides two ways of defining such dynamic completion of nouns. Note that both these methods can be used along-side each other as long as they are not both used for the same command.
-
-**Note**: *Custom Completions written in Go* will automatically work for other shell-completion scripts (e.g., Fish shell), while *Custom Completions written in Bash* will only work for Bash shell-completion.  It is therefore recommended to use *Custom Completions written in Go*.
-
-#### 1. Custom completions of nouns written in Go
-
-In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command.  Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both.
-Simplified code from `helm status` looks like:
-
-```go
-cmd := &cobra.Command{
-	Use:   "status RELEASE_NAME",
-	Short: "Display the status of the named release",
-	Long:  status_long,
-	RunE: func(cmd *cobra.Command, args []string) {
-		RunGet(args[0])
-	},
-	ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
-		if len(args) != 0 {
-			return nil, cobra.ShellCompDirectiveNoFileComp
-		}
-		return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp
-	},
-}
-```
-Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster.
-Notice we put the `ValidArgsFunction` on the `status` subcommand. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like
-
-```bash
-# helm status [tab][tab]
-harbor notary rook thanos
-```
-You may have noticed the use of `cobra.ShellCompDirective`.  These directives are bit fields allowing to control some shell completion behaviors for your particular completion.  You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp`
-```go
-// Indicates an error occurred and completions should be ignored.
-ShellCompDirectiveError
-// Indicates that the shell should not add a space after the completion,
-// even if there is a single completion provided.
-ShellCompDirectiveNoSpace
-// Indicates that the shell should not provide file completion even when
-// no completion is provided.
-// This currently does not work for zsh or bash < 4
-ShellCompDirectiveNoFileComp
-// Indicates that the shell will perform its default behavior after completions
-// have been provided (this implies !ShellCompDirectiveNoSpace && !ShellCompDirectiveNoFileComp).
-ShellCompDirectiveDefault
-```
-
-When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line.  You therefore don't need to do this parsing yourself.  For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function.
-
-##### Debugging
-
-Cobra achieves dynamic completions written in Go through the use of a hidden command called by the completion script.  To debug your Go completion code, you can call this hidden command directly:
-```bash
-# helm __complete status har<ENTER>
-harbor
-:4
-Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
-```
-***Important:*** If the noun to complete is empty, you must pass an empty parameter to the `__complete` command:
-```bash
-# helm __complete status ""<ENTER>
-harbor
-notary
-rook
-thanos
-:4
-Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
-```
-Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code.  You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code:
-```go
-// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
-// is set to a file path) and optionally prints to stderr.
-cobra.CompDebug(msg string, printToStdErr bool) {
-cobra.CompDebugln(msg string, printToStdErr bool)
-
-// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
-// is set to a file path) and to stderr.
-cobra.CompError(msg string)
-cobra.CompErrorln(msg string)
-```
-***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script.  Instead, use the cobra-provided debugging traces functions mentioned above.
-
-#### 2. Custom completions of nouns written in Bash
-
-This method allows you to inject bash functions into the completion script.  Those bash functions are responsible for providing the completion choices for your own completions.

 The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__kubectl_custom_func()` (`__<command-use>_custom_func()`) to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__kubectl_customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__kubectl_custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`.  `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`.  So it will call `__kubectl_parse_get pod`.  `__kubectl_parse_get` will actually call out to kubernetes and get any pods.  It will then set `COMPREPLY` to valid pods!
 
-## Mark flags as required
-
-Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab].  Marking a flag as 'Required' is incredibly easy.
-
-```go
-cmd.MarkFlagRequired("pod")
-cmd.MarkFlagRequired("container")
-```
-
-and you'll get something like
-
-```bash
-# kubectl exec [tab][tab][tab]
--c            --container=  -p            --pod=  
-```
-
-# Specify valid filename extensions for flags that take a filename
-
-In this example we use --filename= and expect to get a json or yaml file as the argument. To make this easier we annotate the --filename flag with valid filename extensions.
-
-```go
-	annotations := []string{"json", "yaml", "yml"}
-	annotation := make(map[string][]string)
-	annotation[cobra.BashCompFilenameExt] = annotations
-
-	flag := &pflag.Flag{
-		Name:        "filename",
-		Shorthand:   "f",
-		Usage:       usage,
-		Value:       value,
-		DefValue:    value.String(),
-		Annotations: annotation,
-	}
-	cmd.Flags().AddFlag(flag)
-```
-
-Now when you run a command with this filename flag you'll get something like
-
-```bash
-# kubectl create -f 
-test/                         example/                      rpmbuild/
-hello.yml                     test.json
-```
-
-So while there are many other files in the CWD it only shows me subdirs and those with valid extensions.
-
-# Specify custom flag completion
-
-As for nouns, Cobra provides two ways of defining dynamic completion of flags.  Note that both these methods can be used along-side each other as long as they are not both used for the same flag.
-
-**Note**: *Custom Completions written in Go* will automatically work for other shell-completion scripts (e.g., Fish shell), while *Custom Completions written in Bash* will only work for Bash shell-completion.  It is therefore recommended to use *Custom Completions written in Go*.
-
-## 1. Custom completions of flags written in Go
-
-To provide a Go function that Cobra will execute when it needs the list of completion choices for a flag, you must register the function in the following manner:
-
-```go
-flagName := "output"
-cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
-	return []string{"json", "table", "yaml"}, cobra.ShellCompDirectiveDefault
-})
-```
-Notice that calling `RegisterFlagCompletionFunc()` is done through the `command` with which the flag is associated.  In our example this dynamic completion will give results like so:
-
-```bash
-# helm status --output [tab][tab]
-json table yaml
-```
-
-### Debugging
-
-You can also easily debug your Go completion code for flags:
-```bash
-# helm __complete status --output ""
-json
-table
-yaml
-:4
-Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
-```
-***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script.  Instead, use the cobra-provided debugging traces functions mentioned in the above section.

-Alternatively, you can use bash code for flag custom completion. Similar to the filename
-completion and filtering using `cobra.BashCompFilenameExt`, you can specify

-## Generating Fish Completions for your own cobra.Command
+## Generating Fish Completions For Your cobra.Command
 
-Cobra supports native Fish completions generated from the root `cobra.Command`.  You can use the `command.GenFishCompletion()` or `command.GenFishCompletionFile()` functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information.  You can choose to make this option configurable by your users.
+Please refer to [Shell Completions](shell_completions.md) for details.
 
-### Limitations
-
-* Custom completions implemented using the `ValidArgsFunction` and `RegisterFlagCompletionFunc()` are supported automatically but the ones implemented in Bash scripting are not.

 Cobra can generate PowerShell completion scripts. Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
 
+*Note*: PowerShell completions have not (yet?) been aligned to Cobra's generic shell completion support.  This implies the PowerShell completions are not as rich as for other shells (see [What's not yet supported](#whats-not-yet-supported)), and may behave slightly differently.  They are still very useful for PowerShell users.
+
 # What's supported
 
 - Completion for subcommands using their `.Short` description

+# Generating shell completions
+
+Cobra can generate shell completions for multiple shells.
+The currently supported shells are:
+- Bash
+- Zsh
+- Fish
+- PowerShell
+
+If you are using the generator you can create a completion command by running
+
+```bash
+cobra add completion
+```
+and then modifying the generated `cmd/completion.go` file to look something like this
+(writing the shell script to stdout allows the most flexible use):
+
+```go
+var completionCmd = &cobra.Command{
+	Use:                   "completion [bash|zsh|fish|powershell]",
+	Short:                 "Generate completion script",
+	Long: `To load completions:
+
+Bash:
+
+$ source <(yourprogram completion bash)
+
+# To load completions for each session, execute once:
+Linux:
+  $ yourprogram completion bash > /etc/bash_completion.d/yourprogram
+MacOS:
+  $ yourprogram completion bash > /usr/local/etc/bash_completion.d/yourprogram
+
+Zsh:
+
+# If shell completion is not already enabled in your environment you will need
+# to enable it.  You can execute the following once:
+
+$ echo "autoload -U compinit; compinit" >> ~/.zshrc
+
+# To load completions for each session, execute once:
+$ yourprogram completion zsh > "${fpath[1]}/_yourprogram"
+
+# You will need to start a new shell for this setup to take effect.
+
+Fish:
+
+$ yourprogram completion fish | source
+
+# To load completions for each session, execute once:
+$ yourprogram completion fish > ~/.config/fish/completions/yourprogram.fish
+`,
+	DisableFlagsInUseLine: true,
+	ValidArgs:             []string{"bash", "zsh", "fish", "powershell"},
+	Args:                  cobra.ExactValidArgs(1),
+	Run: func(cmd *cobra.Command, args []string) {
+		switch args[0] {
+		case "bash":
+			cmd.Root().GenBashCompletion(os.Stdout)
+		case "zsh":
+			cmd.Root().GenZshCompletion(os.Stdout)
+		case "fish":
+			cmd.Root().GenFishCompletion(os.Stdout, true)
+		case "powershell":
+			cmd.Root().GenPowerShellCompletion(os.Stdout)
+		}
+	},
+}
+```
+
+**Note:** The cobra generator may include messages printed to stdout for example if the config file is loaded, this will break the auto complete script so must be removed.
+
+# Customizing completions
+
+The generated completion scripts will automatically handle completing commands and flags.  However, you can make your completions much more powerful by providing information to complete your program's nouns and flag values.
+
+## Completion of nouns
+
+### Static completion of nouns
+
+Cobra allows you to provide a pre-defined list of completion choices for your nouns using the `ValidArgs` field.
+For example, if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them.
+Some simplified code from `kubectl get` looks like:
+
+```go
+validArgs []string = { "pod", "node", "service", "replicationcontroller" }
+
+cmd := &cobra.Command{
+	Use:     "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
+	Short:   "Display one or many resources",
+	Long:    get_long,
+	Example: get_example,
+	Run: func(cmd *cobra.Command, args []string) {
+		err := RunGet(f, out, cmd, args)
+		util.CheckErr(err)
+	},
+	ValidArgs: validArgs,
+}
+```
+
+Notice we put the `ValidArgs` field on the `get` sub-command. Doing so will give results like:
+
+```bash
+$ kubectl get [tab][tab]
+node   pod   replicationcontroller   service
+```
+
+#### Aliases for nouns
+
+If your nouns have aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
+
+```go
+argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
+
+cmd := &cobra.Command{
+    ...
+	ValidArgs:  validArgs,
+	ArgAliases: argAliases
+}
+```
+
+The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
+the completion algorithm if entered manually, e.g. in:
+
+```bash
+$ kubectl get rc [tab][tab]
+backend        frontend       database 
+```
+
+Note that without declaring `rc` as an alias, the completion algorithm would not know to show the list of
+replication controllers following `rc`.
+
+### Dynamic completion of nouns
+
+In some cases it is not possible to provide a list of completions in advance.  Instead, the list of completions must be determined at execution-time. In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command.  Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both.
+Simplified code from `helm status` looks like:
+
+```go
+cmd := &cobra.Command{
+	Use:   "status RELEASE_NAME",
+	Short: "Display the status of the named release",
+	Long:  status_long,
+	RunE: func(cmd *cobra.Command, args []string) {
+		RunGet(args[0])
+	},
+	ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+		if len(args) != 0 {
+			return nil, cobra.ShellCompDirectiveNoFileComp
+		}
+		return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp
+	},
+}
+```
+Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster.
+Notice we put the `ValidArgsFunction` on the `status` sub-command. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like:
+
+```bash
+$ helm status [tab][tab]
+harbor notary rook thanos
+```
+You may have noticed the use of `cobra.ShellCompDirective`.  These directives are bit fields allowing to control some shell completion behaviors for your particular completion.  You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp`
+```go
+// Indicates that the shell will perform its default behavior after completions
+// have been provided (this implies none of the other directives).
+ShellCompDirectiveDefault
+
+// Indicates an error occurred and completions should be ignored.
+ShellCompDirectiveError
+
+// Indicates that the shell should not add a space after the completion,
+// even if there is a single completion provided.
+ShellCompDirectiveNoSpace
+
+// Indicates that the shell should not provide file completion even when
+// no completion is provided.
+ShellCompDirectiveNoFileComp
+
+// Indicates that the returned completions should be used as file extension filters.
+// For example, to complete only files of the form *.json or *.yaml:
+//    return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt
+// For flags, using MarkFlagFilename() and MarkPersistentFlagFilename()
+// is a shortcut to using this directive explicitly.
+//
+ShellCompDirectiveFilterFileExt
+
+// Indicates that only directory names should be provided in file completion.
+// For example:
+//    return nil, ShellCompDirectiveFilterDirs
+// For flags, using MarkFlagDirname() is a shortcut to using this directive explicitly.
+//
+// To request directory names within another directory, the returned completions
+// should specify a single directory name within which to search. For example,
+// to complete directories within "themes/":
+//    return []string{"themes"}, ShellCompDirectiveFilterDirs
+//
+ShellCompDirectiveFilterDirs
+```
+
+***Note***: When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line.  You therefore don't need to do this parsing yourself.  For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function.
+
+#### Debugging
+
+Cobra achieves dynamic completion through the use of a hidden command called by the completion script.  To debug your Go completion code, you can call this hidden command directly:
+```bash
+$ helm __complete status har<ENTER>
+harbor
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+***Important:*** If the noun to complete is empty (when the user has not yet typed any letters of that noun), you must pass an empty parameter to the `__complete` command:
+```bash
+$ helm __complete status ""<ENTER>
+harbor
+notary
+rook
+thanos
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code.  You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code:
+```go
+// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
+// is set to a file path) and optionally prints to stderr.
+cobra.CompDebug(msg string, printToStdErr bool) {
+cobra.CompDebugln(msg string, printToStdErr bool)
+
+// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
+// is set to a file path) and to stderr.
+cobra.CompError(msg string)
+cobra.CompErrorln(msg string)
+```
+***Important:*** You should **not** leave traces that print directly to stdout in your completion code as they will be interpreted as completion choices by the completion script.  Instead, use the cobra-provided debugging traces functions mentioned above.
+
+## Completions for flags
+
+### Mark flags as required
+
+Most of the time completions will only show sub-commands. But if a flag is required to make a sub-command work, you probably want it to show up when the user types [tab][tab].  You can mark a flag as 'Required' like so:
+
+```go
+cmd.MarkFlagRequired("pod")
+cmd.MarkFlagRequired("container")
+```
+
+and you'll get something like
+
+```bash
+$ kubectl exec [tab][tab]
+-c            --container=  -p            --pod=  
+```
+
+### Specify dynamic flag completion
+
+As for nouns, Cobra provides a way of defining dynamic completion of flags.  To provide a Go function that Cobra will execute when it needs the list of completion choices for a flag, you must register the function using the `command.RegisterFlagCompletionFunc()` function.
+
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+	return []string{"json", "table", "yaml"}, cobra.ShellCompDirectiveDefault
+})
+```
+Notice that calling `RegisterFlagCompletionFunc()` is done through the `command` with which the flag is associated.  In our example this dynamic completion will give results like so:
+
+```bash
+$ helm status --output [tab][tab]
+json table yaml
+```
+
+#### Debugging
+
+You can also easily debug your Go completion code for flags:
+```bash
+$ helm __complete status --output ""
+json
+table
+yaml
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script.  Instead, use the cobra-provided debugging traces functions mentioned further above.
+
+### Specify valid filename extensions for flags that take a filename
+
+To limit completions of flag values to file names with certain extensions you can either use the different `MarkFlagFilename()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterFileExt`, like so:
+```go
+flagName := "output"
+cmd.MarkFlagFilename(flagName, "yaml", "json")
+```
+or
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+	return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt})
+```
+
+### Limit flag completions to directory names
+
+To limit completions of flag values to directory names you can either use the `MarkFlagDirname()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs`, like so:
+```go
+flagName := "output"
+cmd.MarkFlagDirname(flagName)
+```
+or
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+	return nil, cobra.ShellCompDirectiveFilterDirs
+})
+```
+To limit completions of flag values to directory names *within another directory* you can use a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs` like so:
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+	return []string{"themes"}, cobra.ShellCompDirectiveFilterDirs
+})
+```
+### Descriptions for completions
+
+Both `zsh` and `fish` allow for descriptions to annotate completion choices.  For commands and flags, Cobra will provide the descriptions automatically, based on usage information.  For example, using zsh:
+```
+$ helm s[tab]
+search  -- search for a keyword in charts
+show    -- show information of a chart
+status  -- displays the status of the named release
+```
+while using fish:
+```
+$ helm s[tab]
+search  (search for a keyword in charts)  show  (show information of a chart)  status  (displays the status of the named release)
+```
+
+Cobra allows you to add annotations to your own completions.  Simply add the annotation text after each completion, following a `\t` separator.  This technique applies to completions returned by `ValidArgs`, `ValidArgsFunction` and `RegisterFlagCompletionFunc()`.  For example:
+```go
+ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+	return []string{"harbor\tAn image registry", "thanos\tLong-term metrics"}, cobra.ShellCompDirectiveNoFileComp
+}}
+```
+or
+```go
+ValidArgs: []string{"bash\tCompletions for bash", "zsh\tCompletions for zsh"}
+```
+## Bash completions
+
+### Dependencies
+
+The bash completion script generated by Cobra requires the `bash_completion` package. You should update the help text of your completion command to show how to install the `bash_completion` package ([Kubectl docs](https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion))
+
+### Aliases
+
+You can also configure `bash` aliases for your program and they will also support completions.
+
+```bash
+alias aliasname=origcommand
+complete -o default -F __start_origcommand aliasname
+
+# and now when you run `aliasname` completion will make
+# suggestions as it did for `origcommand`.
+
+$ aliasname <tab><tab>
+completion     firstcommand   secondcommand
+```
+### Bash legacy dynamic completions
+
+For backwards-compatibility, Cobra still supports its bash legacy dynamic completion solution.
+Please refer to [Bash Completions](bash_completions.md) for details.
+
+## Zsh completions
+
+Cobra supports native Zsh completion generated from the root `cobra.Command`.
+The generated completion script should be put somewhere in your `$fpath` and be named
+`_<yourProgram>`.  You will need to start a new shell for the completions to become available.
+
+Zsh supports descriptions for completions. Cobra will provide the description automatically,
+based on usage information. Cobra provides a way to completely disable such descriptions by
+using `GenZshCompletionNoDesc()` or `GenZshCompletionFileNoDesc()`. You can choose to make
+this a configurable option to your users.
+```
+# With descriptions
+$ helm s[tab]
+search  -- search for a keyword in charts
+show    -- show information of a chart
+status  -- displays the status of the named release
+
+# Without descriptions
+$ helm s[tab]
+search  show  status
+```
+*Note*: Because of backwards-compatibility requirements, we were forced to have a different API to disable completion descriptions between `Zsh` and `Fish`.
+
+### Limitations
+
+* Custom completions implemented in Bash scripting (legacy) are not supported and will be ignored for `zsh` (including the use of the `BashCompCustom` flag annotation).
+  * You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`).
+* The function `MarkFlagCustom()` is not supported and will be ignored for `zsh`.
+  * You should instead use `RegisterFlagCompletionFunc()`.
+
+### Zsh completions standardization
+
+Cobra 1.1 standardized its zsh completion support to align it with its other shell completions.  Although the API was kept backwards-compatible, some small changes in behavior were introduced.
+Please refer to [Zsh Completions](zsh_completions.md) for details.
+
+## Fish completions
+
+Cobra supports native Fish completions generated from the root `cobra.Command`.  You can use the `command.GenFishCompletion()` or `command.GenFishCompletionFile()` functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information.  You can choose to make this option configurable by your users.
+```
+# With descriptions
+$ helm s[tab]
+search  (search for a keyword in charts)  show  (show information of a chart)  status  (displays the status of the named release)
+
+# Without descriptions
+$ helm s[tab]
+search  show  status
+```
+*Note*: Because of backwards-compatibility requirements, we were forced to have a different API to disable completion descriptions between `Zsh` and `Fish`.
+
+### Limitations
+
+* Custom completions implemented in Bash scripting (legacy) are not supported and will be ignored for `fish` (including the use of the `BashCompCustom` flag annotation).
+  * You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`).
+* The function `MarkFlagCustom()` is not supported and will be ignored for `fish`.
+  * You should instead use `RegisterFlagCompletionFunc()`.
+* The following flag completion annotations are not supported and will be ignored for `fish`:
+  * `BashCompFilenameExt` (filtering by file extension)
+  * `BashCompSubdirsInDir` (filtering by directory)
+* The functions corresponding to the above annotations are consequently not supported and will be ignored for `fish`:
+  * `MarkFlagFilename()` and `MarkPersistentFlagFilename()` (filtering by file extension)
+  * `MarkFlagDirname()` and `MarkPersistentFlagDirname()` (filtering by directory)
+* Similarly, the following completion directives are not supported and will be ignored for `fish`:
+  * `ShellCompDirectiveFilterFileExt` (filtering by file extension)
+  * `ShellCompDirectiveFilterDirs` (filtering by directory)

-## Generating Zsh Completion for your cobra.Command
+## Generating Zsh Completion For Your cobra.Command
 
-Cobra supports native Zsh completion generated from the root `cobra.Command`.
-The generated completion script should be put somewhere in your `$fpath` named
-`_<YOUR COMMAND>`.
+Please refer to [Shell Completions](shell_completions.md) for details.
 
-### What's Supported
+## Zsh completions standardization
 
-* Completion for all non-hidden subcommands using their `.Short` description.
-* Completion for all non-hidden flags using the following rules:
-  * Filename completion works by marking the flag with `cmd.MarkFlagFilename...`
-    family of commands.
-  * The requirement for argument to the flag is decided by the `.NoOptDefVal`
-    flag value - if it's empty then completion will expect an argument.
-  * Flags of one of the various `*Array` and `*Slice` types supports multiple
-    specifications (with or without argument depending on the specific type).
-* Completion of positional arguments using the following rules:
-  * Argument position for all options below starts at `1`. If argument position
-    `0` is requested it will raise an error.
-  * Use `command.MarkZshCompPositionalArgumentFile` to complete filenames. Glob
-    patterns (e.g. `"*.log"`) are optional - if not specified it will offer to
-    complete all file types.
-  * Use `command.MarkZshCompPositionalArgumentWords` to offer specific words for
-    completion. At least one word is required.
-  * It's possible to specify completion for some arguments and leave some
-    unspecified (e.g. offer words for second argument but nothing for first
-    argument). This will cause no completion for first argument but words
-    completion for second argument.
-  * If no argument completion was specified for 1st argument (but optionally was
-    specified for 2nd) and the command has `ValidArgs` it will be used as
-    completion options for 1st argument.
-  * Argument completions only offered for commands with no subcommands.
+Cobra 1.1 standardized its zsh completion support to align it with its other shell completions.  Although the API was kept backwards-compatible, some small changes in behavior were introduced.
 
-### What's not yet Supported
+### Deprecation summary
 
-* Custom completion scripts are not supported yet (We should probably create zsh
-  specific one, doesn't make sense to re-use the bash one as the functions will
-  be different).
-* Whatever other feature you're looking for and doesn't exist :)
+See further below for more details on these deprecations.
+
+* `cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` is no longer needed.  It is therefore **deprecated** and silently ignored.
+* `cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` is **deprecated** and silently ignored.
+  * Instead use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt`.
+* `cmd.MarkZshCompPositionalArgumentWords()` is **deprecated** and silently ignored.
+  * Instead use `ValidArgsFunction`.
+
+### Behavioral changes
+
+**Noun completion**
+|Old behavior|New behavior|
+|---|---|
+|No file completion by default (opposite of bash)|File completion by default; use `ValidArgsFunction` with `ShellCompDirectiveNoFileComp` to turn off file completion on a per-argument basis|
+|Completion of flag names without the `-` prefix having been typed|Flag names are only completed if the user has typed the first `-`|
+`cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` used to turn on file completion on a per-argument position basis|File completion for all arguments by default; `cmd.MarkZshCompPositionalArgumentFile()` is **deprecated** and silently ignored|
+|`cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` used to turn on file completion **with glob filtering** on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentFile()` is **deprecated** and silently ignored; use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt` for file **extension** filtering (not full glob filtering)|
+|`cmd.MarkZshCompPositionalArgumentWords(pos, words[])` used to provide completion choices on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentWords()` is **deprecated** and silently ignored; use `ValidArgsFunction` to achieve the same behavior|
+
+**Flag-value completion**
+
+|Old behavior|New behavior|
+|---|---|
+|No file completion by default (opposite of bash)|File completion by default; use `RegisterFlagCompletionFunc()` with `ShellCompDirectiveNoFileComp` to turn off file completion|
+|`cmd.MarkFlagFilename(flag, []string{})` and similar used to turn on file completion|File completion by default; `cmd.MarkFlagFilename(flag, []string{})` no longer needed in this context and silently ignored|
+|`cmd.MarkFlagFilename(flag, glob[])`  used to turn on file completion **with glob filtering** (syntax of `[]string{"*.yaml", "*.yml"}` incompatible with bash)|Will continue to work, however, support for bash syntax is added and should be used instead so as to work for all shells (`[]string{"yaml", "yml"}`)|
+|`cmd.MarkFlagDirname(flag)` only completes directories (zsh-specific)|Has been added for all shells|
+|Completion of a flag name does not repeat, unless flag is of type `*Array` or `*Slice` (not supported by bash)|Retained for `zsh` and added to `fish`|
+|Completion of a flag name does not provide the `=` form (unlike bash)|Retained for `zsh` and added to `fish`|
+
+**Improvements**
+
+* Custom completion support (`ValidArgsFunction` and `RegisterFlagCompletionFunc()`)
+* File completion by default if no other completions found
+* Handling of required flags
+* File extension filtering no longer mutually exclusive with bash usage
+* Completion of directory names *within* another directory
+* Support for `=` form of flags

+For that, a bunch of commands are available, each with its own purpose:
+
+* WriteConfig - writes the current viper configuration to the predefined path, if exists. Errors if no predefined path. Will overwrite the current config file, if it exists.
+* SafeWriteConfig - writes the current viper configuration to the predefined path. Errors if no predefined path. Will not overwrite the current config file, if it exists.
+* WriteConfigAs - writes the current viper configuration to the given filepath. Will overwrite the given file, if it exists.
+* SafeWriteConfigAs - writes the current viper configuration to the given filepath. Will not overwrite the given file, if it exists.
+
+As a rule of the thumb, everything marked with safe won't overwrite any file, but just create if not existent, whilst the default behavior is to create or truncate.
+
+A small examples section:
+
+```go
+viper.WriteConfig() // writes current config to predefined path set by 'viper.AddConfigPath()' and 'viper.SetConfigName'
+viper.SafeWriteConfig()
+viper.WriteConfigAs("/path/to/my/.config")
+viper.SafeWriteConfigAs("/path/to/my/.config") // will error since it has already been written
+viper.SafeWriteConfigAs("/path/to/my/.other_config")
+```

-really wants to add this feature, I’d be happy to merge it. It’s easy to specify

+
+Load environment variables dynamically in Go.
+
+## Usage
+
+Put the gotenv package on your `import` statement:
+
+```go
+import "github.com/subosito/gotenv"
+```
+
+To modify your app environment variables, `gotenv` expose 2 main functions:
+
+- `gotenv.Load`
+- `gotenv.Apply`
+
+By default, `gotenv.Load` will look for a file called `.env` in the current working directory.
+
+Behind the scene, it will then load `.env` file and export the valid variables to the environment variables. Make sure you call the method as soon as possible to ensure it loads all variables, say, put it on `init()` function.
+
+Once loaded you can use `os.Getenv()` to get the value of the variable.
+
+Let's say you have `.env` file:
+
+```
+APP_ID=1234567
+APP_SECRET=abcdef
+```
+
+Here's the example of your app:
+
+```go
+package main
+
+import (
+	"github.com/subosito/gotenv"
+	"log"
+	"os"
+)
+
+func init() {
+	gotenv.Load()
+}
+
+func main() {
+	log.Println(os.Getenv("APP_ID"))     // "1234567"
+	log.Println(os.Getenv("APP_SECRET")) // "abcdef"
+}
+```
+
+You can also load other than `.env` file if you wish. Just supply filenames when calling `Load()`. It will load them in order and the first value set for a variable will win.:
+
+```go
+gotenv.Load(".env.production", "credentials")
+```
+
+While `gotenv.Load` loads entries from `.env` file, `gotenv.Apply` allows you to use any `io.Reader`:
+
+```go
+gotenv.Apply(strings.NewReader("APP_ID=1234567"))
+
+log.Println(os.Getenv("APP_ID"))
+// Output: "1234567"
+```
+
+Both `gotenv.Load` and `gotenv.Apply` **DO NOT** overrides existing environment variables. If you want to override existing ones, you can see section below.
+
+### Environment Overrides
+
+Besides above functions, `gotenv` also provides another functions that overrides existing:
+
+- `gotenv.OverLoad`
+- `gotenv.OverApply`
+
+
+Here's the example of this overrides behavior:
+
+```go
+os.Setenv("HELLO", "world")
+
+// NOTE: using Apply existing value will be reserved
+gotenv.Apply(strings.NewReader("HELLO=universe"))
+fmt.Println(os.Getenv("HELLO"))
+// Output: "world"
+
+// NOTE: using OverApply existing value will be overridden
+gotenv.OverApply(strings.NewReader("HELLO=universe"))
+fmt.Println(os.Getenv("HELLO"))
+// Output: "universe"
+```
+
+### Throw a Panic
+
+Both `gotenv.Load` and `gotenv.OverLoad` returns an error on something wrong occurred, like your env file is not exist, and so on. To make it easier to use, `gotenv` also provides `gotenv.Must` helper, to let it panic when an error returned.
+
+```go
+err := gotenv.Load(".env-is-not-exist")
+fmt.Println("error", err)
+// error: open .env-is-not-exist: no such file or directory
+
+gotenv.Must(gotenv.Load, ".env-is-not-exist")
+// it will throw a panic
+// panic: open .env-is-not-exist: no such file or directory
+```
+
+### Another Scenario
+
+Just in case you want to parse environment variables from any `io.Reader`, gotenv keeps its `Parse` and `StrictParse` function as public API so you can use that.
+
+```go
+// import "strings"
+
+pairs := gotenv.Parse(strings.NewReader("FOO=test\nBAR=$FOO"))
+// gotenv.Env{"FOO": "test", "BAR": "test"}
+
+err, pairs = gotenv.StrictParse(strings.NewReader(`FOO="bar"`))
+// gotenv.Env{"FOO": "bar"}
+```
+
+`Parse` ignores invalid lines and returns `Env` of valid environment variables, while `StrictParse` returns an error for invalid lines.
+
+## Notes
+
+The gotenv package is a Go port of [`dotenv`](https://github.com/bkeepers/dotenv) project with some additions made for Go. For general features, it aims to be compatible as close as possible.

+Package ini provides INI file read and write functionality in Go.
+
+## Features
+
+- Load from multiple data sources(`[]byte`, file and `io.ReadCloser`) with overwrites.
+- Read with recursion values.
+- Read with parent-child sections.
+- Read with auto-increment key names.
+- Read with multiple-line values.
+- Read with tons of helper methods.
+- Read and convert values to Go types.
+- Read and **WRITE** comments of sections and keys.
+- Manipulate sections, keys and comments with ease.
+- Keep sections and keys in order as you parse and save.
+
+## Installation
+
+The minimum requirement of Go is **1.6**.
+
+```sh
+$ go get gopkg.in/ini.v1
+```
+
+Please add `-u` flag to update in the future.
